This new generation of satellites will be placed in low earth orbit or medium earth orbit, hence, introducing new satellite design concepts. One of the first texts to cover this rapidly evolving field, this text provides the reader with an overview of mobile satellite systems, from their initial introduction (Inmarsat), current satellite-PCS (referring to such systems as Globalstar), through to Satellite-UMTS and an understa 606 $aArtificial satellites in telecommunication 606 $aMobile communication systems 615 0$aArtificial satellites in telecommunication. 615 0$aMobile communication systems. 676 $a621.382/54 700 $aSheriff$b Ray E$0935702 701 $aHu$b Y.
